"It was such a relief to think I wouldn't have to go through all that treatment to get pregnant again. The doctors don't know why it has been so much easier this time - it's just the luck of the draw I guess."

Since taking time out of her solo career in 2004, Louise has turned to TV presenting and modelling.

Since becoming the host of Clothes Show last year, she has also been named the new face of Triumph lingerie.

Louise and Sky Sports presenter Jamie, 34, are expecting a sibling for their three-year-old son Charley in November.
